This book is good but it doesn't stand out. It's a quick story, written as if for children in the Seventies, rather than now. However Karen's writing style is vivid and descriptive and Meggy is an engaging character. The idea of her being a cripple is certainly a unique one and I enjoyed learning how she got around London (slowly). It would be easy to sum this entire story up in one sentence: Meggy Swann moves to London and makes friends.
Later on she discovers that her Father is making a potion to kill the Baron. Finally, some action! Eh, not really. The book ends with a happy childish ending with everyone singing and dancing around a table. Yes, really.
